Abstract: Food sustainability of a nation is primarily dependent on food production and food demand. With limited and even declining primary resources like arable land and water, increasing demand due to population growth, and potential impact of climate change, food sustainability has become a major concern especially for the populous countries.  Food sustainability is a complex function of several variables and the overall sustainability is restricted by these factors and need to examine from regional to global scale. A major gap is a consistent and quantitative formulation for assessment and projection of food sustainability. Here, we present a mathematical model to estimate food sustainability in different scenarios of population growth and consumption pattern. We have also estimated the technology demand for sustainable food supply in different scenarios of population and per capita food consumption by considering world as global, and India, China and the USA as regional for analysis of food sustainability.
